Application 111 a April 1:, 192a. Serial m.

My invention relates to a slicing machine I of the slices from the iece, prevents ragged slices, and prevents s ices from being partially severed. A clear, complete cut is insured. Another object of my invention is to prevent the slices from falling into the space between the gauge plate and the carriage, and to insure that each slice cut shall pass through the space between gauge plate and knife to the trough or receiving means. Other objects will appear from time to time in the course of the specification and claims.

1 illustrate my invention more or less dia grammatically in the accompanying drawings, wherein- Figure 1, is a front elevation; Figure 2 is a section on the line 2-2 of Figure l; I

Figure 3 is a section on the line 33 of Figure 1;

Figure 4, is a view similar to Figure 1 illustrating a variant form of the same construction v Figure 5 is a section on the line 5-5 of Figure 4;v

Figure 6 is a section on the line 6-6 of Figure 5; and

Figure 7 is a transverse section through a further variation of my device.

Like parts are indicated by like symbols throu hout the specification and drawings.

Re erring first to Figures 1 to 3, A indicates any suitable slicin machine base member having the groun engaging supports or studs A B generally indicates any suitable housing member or body upwardly projecting therefrom having associated therewith a face'plate B normally fixed in position and a gauge plate B which may be moved toward and aWa from the plane of the knife as for examp e by rotation of the knob B. I do not wish to be limited to any particular means for im artiug moveinent to the gauge plate but I ave herein shown lugs 15* on the rear of the gauge plate, levers wardly into the plane of said face carriage slidable along the track "or arms B pivoted thereto, themselves pivoted as at B, a gear B associated with one of said levers and a worm B, in mesh therewith and actuated by the knob B C indicates the knife, it being herein shown as recessed in its forward face as at C in order to permit the peripheral portion 0 to project outwardl into and slightly beyond the planes of t e face plate B. It will be understood that the axis of the knife, in the form herein shown, lies in a generally horizontal plane but is tilted slightly from perpendicularity to the face plate B in order to throw one edge of the knife forlate.

D generally indicates a guide trac herein shown as c lindrica'l, and mounted at its ends upon t e sup orts D Beneath it is a supplemental trac D herein shown as of rectangular cross-section. D indicates a I D provided with a downward extension D iormed to surround the track D and thus to prevent rotation of the carriage D about the track D. D is any suitable manual handle whereby the carriage may be moved alon the track D. D is an suitable materia carryingtray positione upon the carriage D. Unless the gauge plate B is adjustexl so far forward as to lie practically in the plane of the cuttin edge of the knife C there will be a spaceietween the gauge plate and the carriage plate D. If this space is left open, bits or slices of material may under some circumstances drop therethrough instead of passing through the space between the knife edge C and the opposed arcuate edge of the gauge plate. In order to render this impossible and to insure that,

all slices shall pass through such gap I provide a su plemental horizontal ledge or plane sur aced member, to prevent such slices from drop ing down between the gauge plate B and the carrier plate D.

Referring for example to Figures 2 and 3 I illustrate, mounted upon the gau e plate B a shelf generally indicated as 1% which includes a portion E engaging and secured to the gauge plate and an outwardly projeL-ting portion E which closely engages and underlies the edge of the plate D which may be milled away or thinned as at E to receive it. It will be observed from Figure 2 that the ledge E extends across substantially the entire width of the face plate although its own maximum usefulness is of course adjacent the cutting edge. It is extended to the right, as shown in Figure 2,

as at E in order that it may hug the edge of the knife in all positions of normal adjustment of the gauge plate. This extension is shown as having an arcuate edge 1n 'order to compensate for the arcuate path which the gauge plate takes when it is adjusted by means of pivoted levers or arms,

' as shown in Figure 2. It will be understood that if some other adjusting means are employed in which the gauge plate takes a different path, as for example a straight path at an angle to the path of movement of the carriage, the extension E will be properly shaped, in order to hug the edge of the knife.

Referring to the form of Figures 4, 5 and 6, l employ a narrow member or shelf G which-extends across substantially the entire front of the gauge plate and is secured to 'the face thereof. Adjacent the knife edge the gauge plate is cut away or slotted as at G and positioned to registerwith the slot is a fixed meat support Gr mounted on any suitable bracket or pedestal G The upper surface Gr of the support G2 may be slightly above the level of t e upper surface of the angle G, in order that it may register closely with the level of the carriage D, as shown in Fi re 6.

The edgeof the meat support is preferably inclined or beveled as at G in order to prevent any stoppage or interference of the work or slice as it crosses over and upon the support G and supports the slice and prevents any particle or fringe or portion of the slice from dro ping down between the carriage and the kni e. The an le G on the gauge plate serves to kee t e lastslice from falling off the pusher p ate.

Referrin to Figure 7 I illustrate a form in which tie angle H is provided with a ortion H underlyin in Figure ,3. The ang e however terminates at, its upper side, at its junction with the gauge plate in an upwardly extending or Inc-lined portion H the upper portion of which lies in the same general plane as the top of the carriage D The edge of the.

carraige may be inclined or milled away as at H in order to conform generally to the inclined portion H This formation of the angle may be employed with either of the forms above described and shown. J V, 7

It will be realized that whereas I have described and shown a practical and operative device that nevertheless many changes might be-made in size, shape, number and.

disposition of parts without departing from the spirit of myinvention. I therefore wish my description and drawings to be The meat support G is always up against the edge of the carriage.

the. carriage D,. as

takenas in a broad sense illustrative and diagrammatic rather than as limiting me to my specific showing.

For example whereas I have illustrated means for adjusting the shelf E laterally in relation to the gauge plate B as for example by the slots E in the portion E of work as it is carried across the face of the knife, and. in employing the gauge plate against which the work is thrust, whether manually or mechanically, it is important to support the slice .while the slice is being cut. Were it possible, which it is not, to

have the carriage approach so close to the gauge plate that no interval is left. between gauge plate and-carriage, there will be no necessity of supporting the slice in the front of the gauge plate. However the mere fact that the gauge plate is adjusted toward and away from the path of the carriage insures that there will be a space between gauge plate and carriage. And furthermore, the increase of the opening between the edgeof the gauge plate and the cutting edge of the knife, which determines the thickness of the slice, insures that there will always be a space between carriage, gauge plateand knife at that point, in which .the carriage gives no support. I therefore provide a shelf or support which cooperates with the carriage and which is independent, in its supporting function, of the position of the gauge plate.

Referring to Fi res 2 and 3 it will be clear that the shelf l will underlie the edge of the carriage at all normal positions of the gauge plate and that therefore no slice or fragment of meat can drop down through the space between carriage and gauge plate. Even more important is the lateral extension E*' of the shelf which isformed to hug the cutting edge of the knife at all positions of the gauge plate. This insures that the slice, in course of severance, will be supported up to the instance of its comple tion.

The support at this point prevents partially completed slices and little tail ends of meat from sliding down around the corner of the carriage" and getting between the front of the carriage and the knife.

In view of the frequent practice of using vitreous enamel for carriage and gauge plate the addition of the slice supporting shelf is important. The front of the carriage is necessarily rounded or oval shaped owing to the fact that the enamel will not stick on a sharp corner. This rounding of the parts would tend to provide an opportunity for the escape of small bits of meat, partly completed slices and the like were it not for the employment of the shelf or sup- .port.

- taken up by the fixed support G which supports the slice up to the cutting instant. It is always up against the edge of the carriage and also closely hugs the edge of the knife and supports the slice until its separation from the work is completed. Thus it prevents any fringe of meat fom drag-- ging over and prevents the slice or any part of the slice from penetrating or dropping into the space between carriage and knife.

The form of Figure 7 has the advantage of lifting the ed e of the work, before the slice is separated, into the plane of support of the-body of the work. Referring to Figure 7 it will be observed that when the work is thrust forward, on the carriage, toward thegauge plate, it will engage the inclined portion H and be lifted up thereby,

P so that the lower edge of the work, as it abuts against the gauge plate, will lie in the plane of the upper face of the carriage D.
